Preparation of homogeneous modified nanofiber structures with the desired morphology1 and properties by electrospinning process and consequent exploitations in liquid filtration2,3 are presented.

Nanostructured materials applied for liquid filtration require additional filter reinforcing, rather poor mechanical properties of nanofibers being the reason. One of the possible reinforcing way can be insertion of nanofiber layer between two cellulosic filtration materials. Combination of cellulose fibers with nanononwoven textile (nNT) based on polymeric nanofibers in board filters results in excellent improvement of bacteria Serratia Marcescens removal measured in accordance with ASTM F838-05. Used bacteria were in sizes 0,5-0,8 × 0,9-2,0 µm. Proper anchorage of antifouling agent into filtration material is very important from the toxicity aspects and ecological point of view. Changes of antibacterial activity in time has been demonstrated on modified nNTs and origin ones. It has been proved the positive influence of silver particles anchored on nanofiber surface on flux improvement because of...
